2.1i 9500/XL Hitop - Incorrect implementation of a <function> = VCC
描述
Keywords: 9500 9500XLhitop VCC
Urgency: Standard
General Description: A pin is reported to be driving out VCC but the actual device does not do so.
解决方案
The problem arose because the logic in the macrocell driving out the VCC was being borrowed by an adjacent macrocell, leaving no product terms for the VCC.
